Hello I was looking at the database compared to the original branch that this project was made from.
It says that Gold and Silver can only give x3 or x2...
In the unmodified treasure box it states that Silver pumpkins have a chance to give x2 at 5%
x1 at 4%
In the unmodified Treasurebox it states that Golds have a chance to give
x1 at 4%
x2 at 5%
AND
x3 at 6%
statistically speaking even copper has a higher chance to give brave crystals than silver or gold because the values were modified on this server and im assuming x2 is still only a 5% chance
and gold is only 6% chance
